I see GMontag's point (for once). The top 10% could be completely immobile, and the second 10% could be a revolving door. This would result in 50% turnover of the top quintile over 20, 50, 100 years.
Seems unlikely but from these data it's possible.

I don't see how the data sheds any light either way on its likelihood. You'd need at least two sets of data over different lengths of time to do that.
However, a priori, it seems likely to me that if you're smart enough to keep your fortune over 20 years, you're probably smart enough to keep it over 40 years.
